The characteristic of the special fire behavior includes: The intensity of fire increases sharply;the sustainable fire spreads very fast;the air convection is very easy;spot fires;fire whirlwind or large stretch of horizontal flame;the wind was suddenly calm.
森林燃烧中的特殊火行为研究是国内外研究难点和重点之一,特殊火行为的特征有:火强度急剧增加、可持续的火蔓延速度很快、空气对流十分容易、远距离飞火、火旋风或大片的水平火焰、风突然平静。
Present studies on forest fire behaviors mainly focus on surface fire,but some special forest fire behaviors have been paid little attention,including crown fire,fire whirl and spot fire.
目前火蔓延模型主要关注于森林地表火的蔓延研究,对一些特殊的火行为,如树冠火、火旋风、飞火等研究极为薄弱,而这些火行为在特大森林火灾的蔓延传播中起着重要作用,往往加速火蔓延,并对扑火人员造成生命危险。
